Iarnrod Eireann have reminded customers this evening of their closed and alternative routes for the upcoming weekend.

Alternative travel routes have been put in place for the weekend which sees the Jazz Weekend kick off in Cork city and the Dublin City Marathon take place in the capital on Monday.

In Dublin, there will be no DART service between Pearse Station and Howth/Malahide from Saturday right through to Monday.

The Drogheda/Dundalk commuter service will operate with bus transfers between Malahide and Connolly Station.

The Belfast Enterprise service will also operate with bus transfers, this time between Connolly Station and Drogheda.

In the south of the country, works on the route between Mallow and Cork will mean that on Saturday evening, from 6pm, bus transfers will be in operation between Mallow Cork.

Some services from Heuston Station in Dublin will be part-operated by bus transfer or will have altered departure times, due to works between Hazelhatch and Monasterevin.

This disruption will take place from Saturday evening at 9pm to Sunday morning at 11am.

Iarnrod Eireann has apologised to customers and advised them to check times before travelling.

Their statement reads: "Iarnród Éireann apologises for the inconvenience caused by essential works".
